In a medium bowl, combine the diced chicken, soy sauce, honey, sriracha, sesame oil, ginger, and garlic. Mix well to ensure the chicken is evenly coated. Let it marinate for at least 30 minutes in the refrigerator.
Heat a non-stick skillet over medium-high heat. Add the marinated chicken and cook for about 6-8 minutes, or until the chicken is cooked through and slightly caramelized. Stir occasionally to ensure even cooking.
Once the chicken is cooked, add the chopped red bell pepper and sauté for an additional 2-3 minutes until just tender. Remove from heat.
Gently fold in the diced mango and sliced green onions into the chicken mixture. Adjust seasoning with salt and pepper to taste.
On a serving platter, arrange the lettuce leaves. Spoon the spicy mango chicken mixture into the center of each leaf.
If desired, sprinkle chopped cilantro on top for added flavor and freshness. Serve immediately while the filling is warm.
Notes
Serve immediately for the best flavor and texture.
